It's not the NFC the bank is interested it, it the MFA provided by your phone PIN, fingerprint or face unlock.
When you open the app on your phone, the phone probably needed to be unlocked first, though not everyone sets a PIN or biometric lock on their phone.
Then you will be prompted for a separate PIN or your fingerprint within the banking app. This provides a stronger signal to the bank that you are the legitimate account holder. If your phone is lost or stolen, the chances of someone else being able to authenticate to your banking app are considerably reduced.
With the web app, people will often save their bank website login credentials in the browser. So now someone nefarious only needs to access the unlocked computer or phone the go to the bank's website to gain unauthorised by still authenticated access to the customer's accounts.
Yes, there are now laptops and tablets with biometric authentication, so the potential is there for adding biometric authentication for banking website. However, when you look at the demographics of banking app vs website use, a strong majority of Millennials and Gen-Z do all their banking via the phone app. Gen-X also slightly favour the phone app whereas Boomers strongly prefer the website. So banks focus their development efforts where the majority of users are.

The same is true for PCs. They've supported that sort of thing for decades, and it's optional for both the phone and the PC.
On top of that, a phone that people carry around everywhere is dramatically more likely to be lost or stolen than a desktop PC that never leaves their house.

If the bank actually cares about this then there are various ways to disable or impede it.

This is just the thing where you make something worse so fewer people use it and then use that as an excuse to keep making it worse. Nobody needs an app that could have been a web page, people use them because it's what get shoved down their throat if they don't go out of their way to do something else.
